Abstract
A construction machine for constructing the composite pile features that a static pile driving mechanism and a stirred pile constructing mechanism or high-pressure chemical churning pile constructing mechanism are installed on a single hydraulic walking carrier. After the stirred pile or chemical churning pile is constructed, the carrier moves by a predefined distance and the static pile driving mechanism is used.
Description
Technical field
The present invention relates to a kind of geotechnical engineering construction machinery, especially a kind of constructing machinery for cement slotting composite piles.
Background technology
The cement slotting stake is by deep layer stirring or high-pressure rotary-spray materials such as cement paste to be injected ground and fully mix the back with foundation soil to form continuous up and down cement earth pile, after the cement earth pile construction is finished, insert a preformed pile at the center of cement earth pile immediately, form composite pile, the bearing capacity of this stake and various performance all are significantly improved than single stake.The method that this stake is constructed typically uses two stake machines at present, carry out mixing pile construction or use the high-pressure rotary jet grouting pile machine to carry out the high-pressure rotary-spray pile driving construction with mixing pile machine earlier, remove mixing pile machine or high-pressure rotary jet grouting pile machine behind the pile, and on the stake position of having constructed, make center mark meter, carry out the preformed pile pressing pile construction after making static pile press to center, last stake position then.This job practices, construction machinery is many, and for less building site, construction plant, two stake machines interfere with each other, and speed of application is slower; Two alternately constructions of stake machine, the centering of cement earth pile and preformed pile more easily produces deviation, the verticality that the while construction plant is ground pile press repeatedly is difficult to guarantee, very easily produce the cement earth pile and the preformed pile decentraction of construction at twice, though or the top cement earth pile is concentric with prefabricated lock pin stake, the bottom of lock pin stake produces eccentric, even is inserted into beyond the pile body of cement earth pile, the bearing capacity of composite pile is seriously influenced, the difficult quality guarantee of stake.
All of these factors taken together all has a strong impact on and stirs promoting the use of of slotting composite piles and these the two kinds of high benefit stakes of high-pressure rotary-spray slotting composite piles.Simultaneously; static pressed pile regular meeting in construction runs into one deck flour sand layer in the stratum; make static pressed pile can't pass through the bearing capacity of influence stake; can only increase the pile driving pressure of pile press at present to this situation; but self intensity of static pressed pile limits the further enhancing of pile driving pressure again, and the bearing capacity of static pressed pile can't be given full play to.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of cost lower, use constructing machinery for cement slotting composite piles reliable, easy operating.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of constructing machinery for cement slotting composite piles, on two main skid directions of hydraulic moving mechanism walking mechanism central axis, settling construction of Static Pressure Pile mechanism and mixing pile construction mechanism respectively, making the main direction of travel of cement slotting composite piles machine identical with the installation direction of two construction mechanisms.
Described construction of Static Pressure Pile mechanism is a kind of in roof pressure construction of Static Pressure Pile mechanism or the hugging pressure type construction of Static Pressure Pile mechanism.
Described construction of Static Pressure Pile mechanism and mixing pile construction mechanism are installed on the stake machine chassis of a walking jointly.
Described two installation directions of cover piling mechanism on walking chassis are that its center line is positioned at the center of two main walking slideways along the parallel direction of main walking slideway.
The travel distance of stake machine chassis on main walking slideway is more than or equal to the distance between two construction mechanism central points, and stake machine chassis can become the state of another construction mechanism align piles position by once walking from the state of a construction mechanism align piles position.
Described mixing pile construction mechanism can replace with the high-pressure rotary jet grouting pile construction mechanism.
The invention has the beneficial effects as follows:
1, reduced the usage quantity of stake machine, the work that two stake machines of former cause are finished jointly reduces to a stake machine and independently finishes, and has reduced construction cost.
2, for narrow and small building site, place, can effectively utilize the building site usable floor area, reduce the interference that the stake machine replaces and produced mutually, pile-forming machine perching speed significantly improves, and has improved speed of application on the whole.
3, owing to two cover construction mechanisms are installed on the straight line identical with the long slideway direction of hydraulic moving mechanism walking mechanism, rabbling mechanism or high-pressure rotary-spray mechanism have constructed the back as long as move a machine by fixed range along long slideway, and silent piling mechanism just can be accurately in place.Avoided secondary to the influence that construction quality produced of the sum of errors perpendicularity deviation of stake, construction quality increased substantially stake.
4, for the stratum that has flour sand interlayer static pressed pile to pass through, can use and stir or the method for high-pressure rotary-spray makes the temporary transient deliquescing of intensity of flour sand layer, static pressed pile is passed through smoothly, along with the intensity of cement-soil increases the effect that can play reinforcing to the stratum again.The bearing capacity of static pressed pile can be given full play to.
